Abstract
PURPOSE:To freely set the characteristics of a speaker by providing an electromagnetic exciting means with a superconductive wire coil and a means to apply a superconductive current to a superconductive wire coil. CONSTITUTION:The current is applied to a coil 1-10 for an electromagnet composed of superconductive wires, a control signal is added to a switch control signal supplying terminal 1-13 after a fixed time, and a switch 1-11 is made fall on the side of a B. In such a condition, the superconductive current is applied to the coil 1-10 for the electromagnet, and after the supplying power source of a current supplying terminal 1-12 for the electromagnet is cut off, the constant current flows into the coil 1-10 for the electromagnet. Consequently, when the superconductive current is arbitrarily set, the intensity of the electromagnet can be set to the strong one, in which the characteristics of the superconductive wire is utilized, the suitable one and the weak one. Thus, the characteristics of the speaker can be arbitrarily set.
